; 1. init

−

<source lang="bash">$ ./pmbootstrap.py init</source>

−

Select "samsung-kylessopen" as the target device and select a working recommended graphical interface.

; 3. flash

−

Ensure that the USB cable is disconnected, then hold down {{button|Volume Down}} + {{button|Home}} for a few seconds as the system boots. This puts the device in flash mode. Once in this mode, enter <source lang="bash">$ ./pmbootstrap.py flasher flash_rootfs</source> to install the rootfs. Once this is finished, put yourself back into flash mode and enter <source lang="bash">$ ./pmbootstrap.py flasher flash_kernel</source> to flash the kernel.

== Graphical Interfaces ==

−

=== Matchbox ===

−

Matchbox is a free software (GPL v2+) window manager for the X Window System designed for embedded systems. It's latest stable release was in April of 2012, the same year this phone was known to be released in the UK. It's rather lightweight, displaying only one window at a time, and has its own software keyboard built in, making it the interface most recommended for this device.

−

−

=== Hildon ===

−

Hildon is an LGPL user interface for cell phones. It's optimized for single touch displays. Due to the lack of a working software keyboard (see {{issue|234|pmaports}}), It isn't recommend for this device.

−

−

=== MATE ===

−

MATE is a fork of Gnome2 fork in response to the negative reception of Gnome3. It's initial release was in 2011 (GPLv2, LGPLv2) and it's still in active development. It doesn't come with a software keyboard and it can be slow and buggy at times. It feels more appropriate as a desktop interface.

−

−

=== Xfce4 ===

−

Xfce aims to be fast and lightweight, while still being visually appealing. It follows the Unix philosophy, with each component being its own project. As of May 2019, it's latest stable release was in 2015. It's licensed under the GPL, LGPL and BSD licenses. It doesn't come with a software keyboard. The user experience is similar on this device to running MATE.

−

−

=== i3wm ===

−

i3wm is a tiling window manager for the X Window System. It's rather small and lightweight. It's initial release was in 2009 and is still in active development. It's licensed under the BSD license. It's highly keyboard driven, but doesn't come with a software keyboard. It's recommended for users who own a hardware keyboard.

−

−

=== Weston ===

−

Weston is a demo Wayland compositor. While it runs nicely on this phone, it has very limited functionality. It isn't recommended for everyday use.

−

−

=== Plasma Mobile ===

−

Plasma Mobile is a GPLv2 licensed smartphone interface. It's sadly painfully slow on this phone and rather buggy. It's not recommended.

Builds and flashes just fine but doesn't boot past the Samsung splash screen. This is the kernel we want running on this device.

−

* Version: Latest

−

=== kylessopen-3.4.0-port ===

−

This kernel currently doesn't compile, but it's the newest kernel that supposedly works for this device. Getting this kernel working should make mainlining easier, and if it proves to be better than FrankenKernel, it'd become the new default kernel. "make:*** [Makefile:949: drivers] Error 2".

−

* Version: 3.4.0

−

−

=== FrankenKernel ===

−

This is the only known kernel capable of booting past the Samsung splash screen and besides the mainline kernel, it's the only one that compiles at all. This is the kernel that gets installed on this phone by default.

−

* Version: 3.0.101

−

−

=== klinkone.android_kernel_ba2x_2.0-1 ===

−

This version fails to build with "make: *** [Makefile:873: .tmp_vmlinux1] Error 1".

−

* Version: 3.0.79

−

=== Other kernels ===

+

=== init ===

−

All of these kernels fail to build but have similar messages when failing.

+

<source lang="bash">$ pmbootstrap init</source>

+

Select "samsung-kylessopen" as the target device and select a working recommended graphical interface.

These ones get further into compiling than the previous list, but fail soon after.

+

<source lang="bash">$ pmbootstrap install</source>

−

Full disk encryption currently doesn't work on this device, so it should be turned off for now.

=== flash ===

−

* Version: 3.0.31

+

Ensure that the USB cable is disconnected, then hold down {{button|Volume Down}} + {{button|Home}} for a few seconds as the system boots. This puts the device in flash mode. Once in this mode, enter <source lang="bash">$ pmbootstrap flasher flash_rootfs</source> to install the rootfs.

Here is a list of tasks that are currently being worked on for this device, from highest priority to lowest.

−

=== Mainlining ===

+

{|class="wikitable feature-colors"

−

[[The_Mainline_Kernel|Mainlining is an important task for this device]], because kernels and drivers that supposedly work for this device are scattered across various git repositories, usually forks of other projects, often heavily patched and abandoned. Relying on kernels that can have their repos deleted at any moment, that are often heavily fractured anyways probably isn't a good idea.

+

! MR

−

All of these kernels claim to be for this device however, it's not known which of these kernels actually work and how well they work. FrankenKernel is the only exception as it is the kernel that gets flashed when installing this device. See [[Troubleshooting:boot]].

! Description

−

=== Device regularly reboots itself ===

+

|-

−

This is almost certainly a watchdog issue, since the device reboots every 10 minutes. I'm currently working on disabling the watchdog. {{issue|242|pmaports}}

+

| {{issue|278|pmaports}}

−

+

|

−

=== Internet connection ===

+

| [[The_Mainline_Kernel]]

−

The internet works fine using [[USB_Internet]] however, thee are no interfaces shown that allow [[WiFi]]. This seems to be caused by the lack of the linux-firmware-ath6k firmware but even when loading it, it doesn't work. A kernel patch is likely necessary. See {{issue|248|pmaports}}.

+

| Device isn't mainlined.

−

+

|-

−

=== Audio ===

+

| {{issue|242|pmaports}}

−

The msm-audio card is detected however, turning up the volume on any channel except the master results in a crash. See [[Audio]] and {{issue|249|pmaports}}.

=== Device sometimes freezes while booting ===

| Device reboots every 10 minutes.

−

Nothing is known about this issue yet.

| {{issue|248|pmaports}}

−

=== FBDirect ===

+

|

−

FBDirect is a program that [[osk-sdl]] and [[charging-sdl]] rely on to work. See {{issue|250|pmaports}}

bluetoothctl doesn't do anything when run. It's suspected to be due to the firmware not being installed. See {{issue|248|pmaports}}.

=== Scrolling graphics before DE ===

+

== Hardware ==

−

Before a desktop environment starts, the screen tends to flicker and scroll. It's a purely cosmetic issue. It's cause is likely related to the framebuffer and may be similar in nature to the FBDirect issue.

According to some websites this device may also have an FM radio, an accelerometer, a proximity sensor and a compass. I haven't found or discovered those peripherals myself but I know the device has a vibrator which most websites fail to mention. It's not on the list because I haven't physically found it yet.

The Samsung Galaxy Ace II X (GT-S7560M) is also sold as the Samsung Galaxy Trend (GT-S7560).

According to some websites this device may also have an FM radio, an accelerometer, a proximity sensor and a compass. I haven't found or discovered those peripherals myself but I know the device has a vibrator which most websites fail to mention. It's not on the list because I haven't physically found it yet.
